Quantum networks rely heavily on combining different quantum systems
like light sources and quantum memories. These may be composed of very
much incompatible systems like quantum dots, atoms and parametric
down-conversion as well as fiber-based resources. Non-linear processes
such as sum-frequency and difference-frequency generation are a powerful
toolbox to bridge the gap between those systems: They enable us to do
frequency conversion, bandwidth compression and spectral reshaping.
Besides manipulation, tailored non-linear processes allow us to
characterize quantum states of light through tomographic and time-domain
measurements.
